Abstract

Natural disaster risk is the possibility of disaster losses, depending on hazard, vulnerability, exposure, and emergency response and recovery capability. Vulnerability is to measure the degree of hazard bearing body when suffered damage, which is not only an important part of risk assessment for loss estimation and disaster, but also is linked to the bridge of hazard and disaster. According to the formation mechanism of grassland snow disaster, the research collected and analyzed historical disaster data and the spatiotemporal characteristics of hazard factors. And, the research select snow depth as the intensity of the hazard, and select loss rate of livestock as the damage degree. By exploiting the inversion model of hazard intensity-hazard loss, the research constructed the livestock vulnerability curve of snow disaster, which is fitted to Xilingol. The results show that the maximum snow depth is more concentrated in January, and distributed mainly over Dong Wu County, Xi Wu County, and Xianghuang County, and the snow depth which is more than 60cm will have a significant impact on the mortality of livestock. The results can be used to assess grassland snow disaster quickly, provide the basis for the disaster risk assessment and early warning, and also can provide the basis for the disaster prevention and management.
